On-site measurements - Dynamic analysis of existing pile response induced by driving of adjacent piles
On-site measurements - Dynamic analysis of existing pile response induced by driving of adjacent piles
Franki piles are in-situ concrete driven piles that are installed by driving a heavy steel pipe into the ground with the aid of a pile driver. This causes considerable vibrations, which lead to wave propagation in the ground. When installed in groups, pile driving vibrations transmitted through the ground may impair the curing process of the young concrete of neighbouring piles that have already been installed. In order to investigate this problem, a large-scale field study was carried out. This study presents metrological investigations into the production of in-situ concrete piles (Franki pile type) with different lengths and diameters in a test field in Hamburg, Germany. Several Franki piles were installed in groups within the investigated construction area. The reinforcement of the piles was instrumented with strain gauges and accelerometers at different depths as part of an accompanying metrological investigation to record the impact of vibrations on the existing piles as a result of a neighbouring pile installation. The measurement results are presented and discussed focusing on the wave propagation through the subsurface and the vibrations affecting the concrete of the adjacent pile.
